Where does it state this pointer bit within the documentations? All I see
in the documentations are by references for ByRef and a copy of the variable with ByVal looking at different places. Also, how is it that I know it will work out the same way with my custom objects similar to how things works out with the objects built into the application itself such as Worksheet object as the Worksheet object is directly tied to the WorkSheets collection object? -- Thanks, Ronald R.

ByVal - Creates a whole new replica of the object with all of the same settings as the object that is being passed onto it No it doesn't. It creates a new (temporary) pointer to the original intrinsic object. As far as the original object's properties are concerned there is no difference between using ByRef and ByVal. Regards, Peter T "Ronald R. Dodge, Jr." wrote in message ... The way I understood the ByRef and ByVal are the following: ByRef - References to the object, and any changes done to the object is done for any variable referencing to that object, rather it be done in the original code or in the code referencing to the object. ByVal - Creates a whole new replica of the object with all of the same settings as the object that is being passed onto it, but any changes done to the original object is not reflects in the new object, just like any changes done in the new object is not reflected in the original object. Though I haven't fully tested it to be sure with object variables, but simple data type variables does work like this. -- Thanks, Ronald R.

One thing though, I think you are misunderstanding the difference of passing an object byref & byval. Either way, any changes to the object's properties will persist. The only difference is with byval a new pointer to the original object is created and passed. This means even if you destroy or reassign the byval object within the procedure, the original object variable will continue point to the same object. Regards, Peter T "Ronald R. Dodge, Jr." wrote in message ... Office XP, SP3 (VBA 6.0) WIN XP, SP2 I have read over the text dealing with custom objects According to the text that I have read online from MS themselves, the keyword "NOTHING" should only destroy the object when there is no other variable refering to that object. However, as I have learned the hard way, that is not the case. Any time any variable is set to NOTHING, the object is destroyed, so any object variable referencing to that object is then also set to NOTHING. Example: PayCode collection has a set of objects containing properties. One of those PayCode objects is passed onto an Employee Object. It's passed into the employee object via a property with the object using the ByRef within the signature line, so if there's any changes to the PayCode object, it's not only changed within the PayCodes collection, but also within the Employee's PayCode reference to it. However, if the Employee Object is set to be destroyed, via the clean up code, the code should be to set the object variable within the Employee Object to NOTHING. However, doing that not only does that, but also set's that particular object within the PayCodes collection to NOTHING as if the object itself has been destroyed. How do I resolve this issue, so as I can have it reset only the variable, not destroy the actual object, but yet, also allow for changes to carry into the variable when they are done into the main object? -- Thanks, Ronald R.
